Description:

An investigation was made to determine whether fibrous-glass used in the production of asphalt (8052424) shingles (SIC-2952) is toxic in the concentrations used. For purposes of completeness, environmental evaluations of worker exposure to some of the other materials in the workplace such as asbestos (1332214), crystalline- silica (7631869), formaldehyde (50000), and asphalt (petroleum) were made. The methods for the evaluation of the work environment varied depending upon the substance being sampled. No medical investigation was made. Employees working in and around the shingle manufacturing line are not exposed to excessive levels of fibrous- glass. The slateman is exposed to potentially toxic levels of dust containing crystalline-silica. Employees entering the saturator are exposed to potentially high levels of benz(a)pyrene (50328). Employees' exposures to asphalt-fumes could not be adequately characterized to make a definite conclusion concerning toxicity with the currently available sampling and analytical techniques. Employees' exposures to formaldehyde, aromatic hydrocarbons, and total aliphatic hydrocarbons are not toxic.
